Find the equation of the line in slope-intercept form.<br> m=− 4 7 through (14, 3
kakasveta [241]

Answer:

The answer to your question is:   y = -47x + 661

Step-by-step explanation:

Data

m = - 47         I wasn't sure if the slope was -47 or -4.

Point (14, 3)

Formula

(y - y1) = m(x - x1)

Process

                  (y - 3) = -47(x - 14)

                   y - 3 = -47x + 658

                   y = -47x + 658 + 3

                   y = -47x + 661

The volume of 400 mL of chlorine gas at 400 mm Hg is decreased to 200 mL at constant temperature. What is the new gas pressure?
rusak2 [61]

A. Let us first assume that the gas acts like an ideal gas so that we can use the ideal gas equation:

PV = nRT

where P is pressure, V is volume, n is number of moles, R is universal gas constant and T is absolute temperature

In this case, let us assume that nRT = constant so that:

P1V1 = P2V2

400 mm Hg * 400 mL = P2 * 200 mL

P2 = 800 mm Hg

 

<span>B. The collision of gas with the walls of the container produces Pressure.</span>

Can someone please<br> Help me?

Answer:

  see below

Step-by-step explanation:

It is easiest to compare the equations when they are written in the same form.

The first set can be written in slope-intercept form.

  y = 2x +7

  y = 2x +7 . . . . add 2x

These equations are <em>identical</em>, so have infinitely many solutions.

__

The second set can be written in standard form.

  y +4x = -5

  y +4x = -10

These equations <em>differ only in their constant</em>, so have no solutions.

__

The third set is already written in slope-intercept form. The equations have <em>different slopes</em>, so have exactly one solution.

Algebraic equations
anzhelika [568]

1) 2x + 9  = 2x -5

            9 ≠ -5 ; No solution

2) 2x-  1 = x + 3

   x = 4; One solution x = 4

3) x + 2 = x + 2

   0 = 0; Identity (or all real numbers)
